Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a dual-fan cooling system is used to meet heat dissipation requirements, then heat dissipation performance is improved, but noise, vibration, and power consumption increase
Solution Approach 1:
The patent merges the functions of two separate fans into a single fan system. The first fan blows air to the first heat source, the second heat source and the first heat dissipation array, while the second fan blows air to the second heat dissipation array. This consolidation reduces the number of rotating components from two to one, thereby reducing noise and vibration while maintaining effective heat dissipation across all heat sources and arrays.
2Temperature
If a dual-fan cooling system is used to meet heat dissipation requirements, then heat dissipation performance is improved, but power consumption increases
Solution Approach 1:
The patent combines multiple fan functions into a single fan system that serves multiple heat sources and heat dissipation arrays. By using one fan instead of two, the system reduces power consumption while still providing adequate cooling to all components through strategically positioned fans that blow air to multiple targets simultaneously.
3Temperature
If multiple fans are used for heat dissipation, then cooling coverage is improved, but device complexity increases
Solution Approach 1:
The patent reduces system complexity by merging multiple fan functions into a single fan. The first fan is positioned to blow air to the first heat source, second heat source and first heat dissipation array, while the second fan blows air to the second heat dissipation array. This simplification reduces the number of components, assembly steps, and potential failure points while maintaining comprehensive cooling coverage through optimized airflow paths.
